    <comment>This term is mapped to MGED. Do not obsolete without consulting MGED ontology. The term 'protein' was merged with 'polypeptide'. Although 'protein' was a sequenece_attribute and therefore meant to describe the quality rather than an actual feature, it was being used erroneously. It is replaced by 'peptidyl' as the polymer attribute.</comment>

      <defstr>The P1-derived artificial chromosome are DNA constructs that are derived from the DNA of P1 bacteriophage. They can carry large amounts (about 100-300 kilobases) of other sequences for a variety of bioengineering purposes. It is one type of vector used to clone DNA fragments (100- to 300-kb insert size; average, 150 kb) in Escherichia coli cells.</defstr>

    <def>
      <defstr>Transfer RNA (tRNA) molecules are approximately 80 nucleotides in length. Their secondary structure includes four short double-helical elements and three loops (D, anti-codon, and T loops). Further hydrogen bonds mediate the characteristic L-shaped molecular structure. Transfer RNAs have two regions of fundamental functional importance: the anti-codon, which is responsible for specific mRNA codon recognition, and the 3' end, to which the tRNA's corresponding amino acid is attached (by aminoacyl-tRNA synthetases). Transfer RNAs cope with the degeneracy of the genetic code in two manners: having more than one tRNA (with a specific anti-codon) for a particular amino acid; and 'wobble' base-pairing, i.e. permitting non-standard base-pairing at the 3rd anti-codon position.</defstr>

      <defstr>A snoRNA (small nucleolar RNA) is any one of a class of small RNAs that are associated with the eukaryotic nucleus as components of small nucleolar ribonucleoproteins. They participate in the processing or modifications of many RNAs, mostly ribosomal RNAs (rRNAs) though snoRNAs are also known to target other classes of RNA, including spliceosomal RNAs, tRNAs, and mRNAs via a stretch of sequence that is complementary to a sequence in the targeted RNA.</defstr>

      <defstr>Small, ~22-nt, RNA molecule that is the endogenous transcript of a miRNA gene. Micro RNAs are produced from precursor molecules (SO:0000647) that can form local hairpin structures, which ordinarily are processed (via the Dicer pathway) such that a single miRNA molecule accumulates from one arm of a hairpin precursor molecule. Micro RNAs may trigger the cleavage of their target molecules or act as translational repressors.</defstr>

      <defstr>5_8S ribosomal RNA (5. 8S rRNA) is a component of the large subunit of the eukaryotic ribosome. It is transcribed by RNA polymerase I as part of the 45S precursor that also contains 18S and 28S rRNA. Functionally, it is thought that 5.8S rRNA may be involved in ribosome translocation. It is also known to form covalent linkage to the p53 tumour suppressor protein. 5_8S rRNA is also found in archaea.</defstr>

      <defstr>An enterobacterial RNA that binds the CsrA protein. The CsrB RNAs contain a conserved motif CAGGXXG that is found in up to 18 copies and has been suggested to bind CsrA. The Csr regulatory system has a strong negative regulatory effect on glycogen biosynthesis, glyconeogenesis and glycogen catabolism and a positive regulatory effect on glycolysis. In other bacteria such as Erwinia caratovara the RsmA protein has been shown to regulate the production of virulence determinants, such extracellular enzymes. RsmA binds to RsmB regulatory RNA which is also a member of this family.</defstr>

    <def>
      <defstr>DsrA RNA regulates both transcription, by overcoming transcriptional silencing by the nucleoid-associated H-NS protein, and translation, by promoting efficient translation of the stress sigma factor, RpoS. These two activities of DsrA can be separated by mutation: the first of three stem-loops of the 85 nucleotide RNA is necessary for RpoS translation but not for anti-H-NS action, while the second stem-loop is essential for antisilencing and less critical for RpoS translation. The third stem-loop, which behaves as a transcription terminator, can be substituted by the trp transcription terminator without loss of either DsrA function. The sequence of the first stem-loop of DsrA is complementary with the upstream leader portion of RpoS messenger RNA, suggesting that pairing of DsrA with the RpoS message might be important for translational regulation.</defstr>

    <def>
      <defstr>The RNA component of Ribonuclease P (RNase P), a ubiquitous endoribonuclease, found in archaea, bacteria and eukarya as well as chloroplasts and mitochondria. Its best characterised activity is the generation of mature 5 prime ends of tRNAs by cleaving the 5 prime leader elements of precursor-tRNAs. Cellular RNase Ps are ribonucleoproteins. RNA from bacterial RNase Ps retains its catalytic activity in the absence of the protein subunit, i.e. it is a ribozyme. Isolated eukaryotic and archaeal RNase P RNA has not been shown to retain its catalytic function, but is still essential for the catalytic activity of the holoenzyme. Although the archaeal and eukaryotic holoenzymes have a much greater protein content than the bacterial ones, the RNA cores from all the three lineages are homologous. Helices corresponding to P1, P2, P3, P4, and P10/11 are common to all cellular RNase P RNAs. Yet, there is considerable sequence variation, particularly among the eukaryotic RNAs.</defstr>

    <def>
      <defstr>Translational regulation of the stationary phase sigma factor RpoS is mediated by the formation of a double-stranded RNA stem-loop structure in the upstream region of the rpoS messenger RNA, occluding the translation initiation site. Clones carrying rprA (RpoS regulator RNA) increased the translation of RpoS. The rprA gene encodes a 106 nucleotide regulatory RNA. As with DsrA Rfam:RF00014, RprA is predicted to form three stem-loops. Thus, at least two small RNAs, DsrA and RprA, participate in the positive regulation of RpoS translation. Unlike DsrA, RprA does not have an extensive region of complementarity to the RpoS leader, leaving its mechanism of action unclear. RprA is non-essential.</defstr>

Its 5' end forms complementary base pairs with the 5' splice junction, thus defining the 5' donor site of an intron. There are significant differences in sequence and secondary structure between metazoan and yeast U1 snRNAs, the latter being much longer (568 nucleotides as compared to 164 nucleotides in human). Nevertheless, secondary structure predictions suggest that all U1 snRNAs share a 'common core' consisting of helices I, II, the proximal region of III, and IV.</defstr>

      <defstr>U4 small nuclear RNA (U4 snRNA) is a component of the major U2-dependent spliceosome. It forms a duplex with U6, and with each splicing round, it is displaced from U6 (and the spliceosome) in an ATP-dependent manner, allowing U6 to refold and create the active site for splicing catalysis. A recycling process involving protein Prp24 re-anneals U4 and U6.</defstr>

The Y RNAs and Ro60 and La proteins are well conserved, but the function of the Ro RNP is not known. In humans the RNA component can be one of four small RNAs: hY1, hY3, hY4 and hY5. These small RNAs are predicted to fold into a conserved secondary structure containing three stem structures. The largest of the four, hY1, contains an additional hairpin.</defstr>

    <def>
      <defstr>A tmRNA liberates a mRNA from a stalled ribosome. To accomplish this part of the tmRNA is used as a reading frame that ends in a translation stop signal. The broken mRNA is replaced in the ribosome by the tmRNA and translation of the tmRNA leads to addition of a proteolysis tag to the incomplete protein enabling recognition by a protease. Recently a number of permuted tmRNAs genes have been found encoded in two parts. TmRNAs have been identified in eubacteria and some chloroplasts but are absent from archeal and eukaryote nuclear genomes.</defstr>

      <defstr>Group I catalytic introns are large self-splicing ribozymes. They catalyse their own excision from mRNA, tRNA and rRNA precursors in a wide range of organisms. The core secondary structure consists of 9 paired regions (P1-P9). These fold to essentially two domains, the P4-P6 domain (formed from the stacking of P5, P4, P6 and P6a helices) and the P3-P9 domain (formed from the P8, P3, P7 and P9 helices). Group I catalytic introns often have long ORFs inserted in loop regions.</defstr>

    <def>
      <defstr>The signal recognition particle (SRP) is a universally conserved ribonucleoprotein. It is involved in the co-translational targeting of proteins to membranes. The eukaryotic SRP consists of a 300-nucleotide 7S RNA and six proteins: SRPs 72, 68, 54, 19, 14, and 9. Archaeal SRP consists of a 7S RNA and homologues of the eukaryotic SRP19 and SRP54 proteins. In most eubacteria, the SRP consists of a 4.5S RNA and the Ffh protein (a homologue of the eukaryotic SRP54 protein). Eukaryotic and archaeal 7S RNAs have very similar secondary structures, with eight helical elements. These fold into the Alu and S domains, separated by a long linker region. Eubacterial SRP is generally a simpler structure, with the M domain of Ffh bound to a region of the 4.5S RNA that corresponds to helix 8 of the eukaryotic and archaeal SRP S domain. Some Gram-positive bacteria (e.g. Bacillus subtilis), however, have a larger SRP RNA that also has an Alu domain. The Alu domain is thought to mediate the peptide chain elongation retardation function of the SRP. The universally conserved helix which interacts with the SRP54/Ffh M domain mediates signal sequence recognition. In eukaryotes and archaea, the SRP19-helix 6 complex is thought to be involved in SRP assembly and stabilizes helix 8 for SRP54 binding.</defstr>

      <defstr>Most box C/D snoRNAs also contain long (&gt;10 nt) sequences complementary to rRNA. Boxes C and D, as well as boxes C' and D', are usually located in close proximity, and form a structure known as the box C/D motif. This motif is important for snoRNA stability, processing, nucleolar targeting and function. A small number of box C/D snoRNAs are involved in rRNA processing; most, however, are known or predicted to serve as guide RNAs in ribose methylation of rRNA. Targeting involves direct base pairing of the snoRNA at the rRNA site to be modified and selection of a rRNA nucleotide a fixed distance from box D or D'.</defstr>

      <defstr>Members of the box H/ACA family contain an ACA triplet, exactly 3 nt upstream from the 3' end and an H-box in a hinge region that links two structurally similar functional domains of the molecule. Both boxes are important for snoRNA biosynthesis and function. A few box H/ACA snoRNAs are involved in rRNA processing; most others are known or predicted to participate in selection of uridine nucleosides in rRNA to be converted to pseudouridines. Site selection is mediated by direct base pairing of the snoRNA with rRNA through one or both targeting domains.</defstr>

    <name>group_II_intron</name>
    <def>
      <defstr>Group II introns are found in rRNA, tRNA and mRNA of organelles in fungi, plants and protists, and also in mRNA in bacteria. They are large self-splicing ribozymes and have 6 structural domains (usually designated dI to dVI). A subset of group II introns also encode essential splicing proteins in intronic ORFs. The length of these introns can therefore be up to 3kb. Splicing occurs in almost identical fashion to nuclear pre-mRNA splicing with two transesterification steps. The 2' hydroxyl of a bulged adenosine in domain VI attacks the 5' splice site, followed by nucleophilic attack on the 3' splice site by the 3' OH of the upstream exon. Protein machinery is required for splicing in vivo, and long range intron-intron and intron-exon interactions are important for splice site positioning. Group II introns are further sub-classified into groups IIA and IIB which differ in splice site consensus, distance of bulged A from 3' splice site, some tertiary interactions, and intronic ORF phylogeny.</defstr>

    <def>
      <defstr>5S ribosomal RNA (5S rRNA) is a component of the large ribosomal subunit in both prokaryotes and eukaryotes. In eukaryotes, it is synthesised by RNA polymerase III (the other eukaryotic rRNAs are cleaved from a 45S precursor synthesised by RNA polymerase I). In Xenopus oocytes, it has been shown that fingers 4-7 of the nine-zinc finger transcription factor TFIIIA can bind to the central region of 5S RNA. Thus, in addition to positively regulating 5S rRNA transcription, TFIIIA also stabilises 5S rRNA until it is required for transcription.</defstr>

    <def>
      <defstr>By definition, minigenes are short open-reading frames (ORF), usually encoding approximately 9 to 20 amino acids, which are expressed in vivo (as distinct from being synthesized as peptide or protein ex vivo and subsequently injected). The in vivo synthesis confers a distinct advantage: the expressed sequences can enter both antigen presentation pathways, MHC I (inducing CD8+ T- cells, which are usually cytotoxic T-lymphocytes (CTL)) and MHC II (inducing CD4+ T-cells, usually 'T-helpers' (Th)); and can encounter B-cells, inducing antibody responses. Three main vector approaches have been used to deliver minigenes: viral vectors, bacterial vectors and plasmid DNA.</defstr>

    <comment>The type of RNA editing found in the mitochondria of Myxomycota, characterized by the insertion of mono- and dinucleotides in RNAs relative to their mtDNA template and in addition, C to U base conversion. The most common mononucleotide insertion is cytidine, although a number of uridine mononucleotides are inserted at specific sites. Adenine and guanine have not been observed in mononucleotide insertions. Five different dinucleotide insertions have been observed, GC, GU, CU, AU and AA. Both mono- and dinucleotide insertions create open reading frames in mRNA and contribute to highly conserved structural features of rRNAs and tRNAs.</comment>

    <comment>The type of RNA editing found in the mitochondria of Myxomycota, characterized by the insertion of mono- and dinucleotides in RNAs relative to their mtDNA template and in addition, C to U base conversion. The most common mononucleotide insertion is cytidine, although a number of uridine mononucleotides are inserted at specific sites. Adenine and guanine have not been observed in mononucleotide insertions. Five different dinucleotide insertions have been observed, GC, GU, CU, AU and AA. Both mono- and dinucleotide insertions create open reading frames in mRNA and contribute to highly conserved structural features of rRNAs and tRNAs.</comment>

      <defstr>A beta strand describes a single length of polypeptide chain that forms part of a beta sheet. A single continuous stretch of amino acids adopting an extended conformation of hydrogen bonds between the N-O and the C=O of another part of the peptide. This forms a secondary protein structure in which two or more extended polypeptide regions are hydrogen-bonded to one another in a planar array.</defstr>

    <def>
      <defstr>A peptide region which hydrogen bonded to another region of peptide running in the oposite direction (one running N-terminal to C-terminal and one running C-terminal to N-terminal). Hydrogen bonding occurs between every other C=O from one strand to every other N-H on the adjacent strand. In this case, if two atoms C-alpha (i) and C-alpha (j) are adjacent in two hydrogen-bonded beta strands, then they form two mutual backbone hydrogen bonds to each other's flanking peptide groups; this is known as a close pair of hydrogen bonds. The peptide backbone dihedral angles (phi, psi) are about (-140 degrees, 135 degrees) in antiparallel sheets.</defstr>

    <def>
      <defstr>A peptide region which hydrogen bonded to another region of peptide running in the oposite direction (both running N-terminal to C-terminal). This orientation is slightly less stable because it introduces nonplanarity in the inter-strand hydrogen bonding pattern. Hydrogen bonding occurs between every other C=O from one strand to every other N-H on the adjacent strand. In this case, if two atoms C-alpha (i)and C-alpha (j) are adjacent in two hydrogen-bonded beta strands, then they do not hydrogen bond to each other; rather, one residue forms hydrogen bonds to the residues that flank the other (but not vice versa). For example, residue i may form hydrogen bonds to residues j - 1 and j + 1; this is known as a wide pair of hydrogen bonds. By contrast, residue j may hydrogen-bond to different residues altogether, or to none at all. The dihedral angles (phi, psi) are about (-120 degrees, 115 degrees) in parallel sheets.</defstr>

    <def>
      <defstr>U3 snoRNA is a member of the box C/D class of small nucleolar RNAs. The U3 snoRNA secondary structure is characterised by a small 5' domain (with boxes A and A'), and a larger 3' domain (with boxes B, C, C', and D), the two domains being linked by a single-stranded hinge. Boxes B and C form the B/C motif, which appears to be exclusive to U3 snoRNAs, and boxes C' and D form the C'/D motif. The latter is functionally similar to the C/D motifs found in other snoRNAs. The 5' domain and the hinge region act as a pre-rRNA-binding domain. The 3' domain has conserved protein-binding sites. Both the box B/C and box C'/D motifs are sufficient for nuclear retention of U3 snoRNA. The box C'/D motif is also necessary for nucleolar localization, stability and hypermethylation of U3 snoRNA. Both box B/C and C'/D motifs are involved in specific protein interactions and are necessary for the rRNA processing functions of U3 snoRNA.</defstr>

Gene traps contain a splice acceptor, do not contain promoter elements for the reporter, and are mutagenic. Gene traps may be bicistronic with the second cassette containing a promoter driving an a selectable marker.</defstr>

    <comment>X element combinatorial repeats contain Tbf1p binding sites,nand possible functions include a role in telomerase-independent telomerenmaintenance via recombination or as a barrier against transcriptionalnsilencing. These are usually present as a combination of one or more ofnseveral types of smaller elements (designated A, B, C, or D).</comment>

    <def>
      <defstr>The incorporation of selenocysteine into a protein sequence is directed by an in-frame UGA codon (usually a stop codon) within the coding region of the mRNA. Selenoprotein mRNAs contain a conserved secondary structure in the 3' UTR that is required for the distinction of UGA stop from UGA selenocysteine. The selenocysteine insertion sequence (SECIS) is around 60 nt in length and adopts a hairpin structure which is sufficiently well-defined and conserved to act as a computational screen for selenoprotein genes.</defstr>
